Wooden bar of 200 g makes the vertical oscillations in a viscous medium with a coefficient of resistance of 10 ^ -2 kg / s. Create a differential equation of free damped oscillations and find their period if the base area of the bar of 100 cm ^ 2, medium density of 800 kg / m ^ 3.
Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
If you have any questions to address, please. I´ll try to help.
